Summary section

Item

Description

Number of Pairs

The number of pairs for each local replication software type.

Snapshot Estimated Manageable Capacity*

The estimated HTI pair capacity. The icon appears when the estimated capacity is less than 5% of the capacity supported by the installed shared memory.

For more information about snapshot estimated manageable capacity, see the Hitachi Thin Image User Guide.

Note: This item is not available for Thin Image Advanced.

Number of Consistency Groups

The number of consistency groups (CTGs) that have a status other than Free, and the maximum number of CTGs allowed.

Number of Snapshot Groups

The number of snapshot groups that are in use, and the maximum number of snapshot groups allowed.

Number of Pair Tables

The number of pair tables in use, and the maximum number of pair tables allowed.

Values:

  • (VSP 5000 series) SI/SIMF/Volume Migration: SI/SIMF, Volume Migration
  • (VSP E series) SI/Volume Migration: SI, Volume Migration
  • TI: HTI

Number of Differential Tables

The number of differential tables in use, and the maximum number of differential tables allowed.

Because differential tables are not used for all operations, the number of differential tables does not change when you execute the following operations:

  • Thin Image pair operations.
  • SI pair operations for a DP-VOL that exceeds 4 TB.
  • (VSP 5000 series) SIz pair operations for a DP-VOL that exceeds 262,668 cylinders.

*Snapshot Estimated Manageable Capacity is an estimation of Thin Image pair capacity that is calculated by subtracting shared memory used by Thin Image pools and Thin Image pairs from the shared memory capacity. Snapshot Estimated Manageable Capacity is only a reference estimation and does not guarantee that the space is available. The Snapshot Estimated Manageable Capacity value changes when Thin Image pool volumes or Thin Image pairs are added or deleted.
